By discussing the position hypothesis of fractional-dimension derivative about general function and the formula form the hypothesis of fractional-dimension derivative about power function, the concrete equation formulas of fractional-dimension derivative, differential and integral are described distinctly further, and the difference between the fractional-dimension derivative and the fractional-order derivative are given too. Subsequently, the concrete forms of measure calculation equations of self-similar fractal obtaining by based on the definition of form in fractional-dimension calculus about general fractal measure are discussed again, and the differences with Hausdorff measure method or the covering method at present are given. By applying the measure calculation equations, the measure of self-similar fractals which include middle-third Cantor set, Koch curve, Sierpinski gasket and orthogonal cross star are calculated and analyzed.

Results showed that specific SIEA26~28 ku scFv with high level expression was achieved. The corresponding gene, ribosomal protein S4 was obtained by initially screening the cercaria cDNA library with the specific SIEA26~28 ku scFv. The obtaining of specific SIEA26~28 ku scFv lays the foundation for further screening and identification of the coding genes of SIEA26~28 ku, the natural molecular candidate vaccine against schistosomiasis.
